感谢老师的回答，我能理解定义高斯光源时，距离是指注入面到焦面的距离，您的意思是指只要保证光源到达结构表面时的场分布与实际相符就相当于模拟实际情况了吗，可我还有一个问题是，由于薄透镜法产生的高斯光源相当于经过显微物镜汇聚的光束，保持数值孔径不变，注入面位于焦面左侧，增大注入面到焦面的距离（绝对值增大），此时显微物镜的焦距是否也增大了呢？焦距增大，物镜口径增大，在聚焦位置处的能量也增大了
We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.
